Nokia N900

Well, that's it in a mostly correct order. As you can tell, I have a problem. That is 2000 to the present. I have to say that I have had most experience with Windows Mobile, and some Android, but my N900 is absolutely the best phone I've ever had. Only complaints are that we cannot get Flash 10.1, would like to have multi-touch, and I would like to have a larger screen. Other than that, there is not another current phone I would rather own.
